Whither pertussis?
© 2015 Informa UK, Ltd. Several lines of evidence suggest that pertussis disease will continue to rise in countries which have switched to acellular vaccines. While maternal vaccination is promising as a mitigating strategy it is unlikely to replace the need for a better vaccine. In the absence of a clear alternative, a return to using whole cell vaccines, at least in part, should not be dismissed as an option without contemporary studies of feasibility and acceptability
The Emergence of Zoonotic Onchocerca lupi Infection in the United States--A Case-Series.
This case-series describes the 6 human infections with Onchocerca lupi, a parasite known to infect cats and dogs, that have been identified in the United States since 2013. Unlike cases reported outside the country, the American patients have not had subconjunctival nodules but have manifested more invasive disease (eg, spinal, orbital, and subdermal nodules). Diagnosis remains challenging in the absence of a serologic test. Treatment should be guided by what is done for Onchocerca volvulus as there are no data for O. lupi. Available evidence suggests that there may be transmission in southwestern United States, but the risk of transmission to humans is not known. Research is needed to better define the burden of disease in the United States and develop appropriately-targeted prevention strategies
Effective surveillance systems for vector-borne diseases in urban settings and translation of the data into action: a scoping review
Bordetella pertussis pathogenesis: current and future challenges
Pertussis, or whooping cough, has recently reemerged as a major public health threat despite high levels of vaccination against the etiological agent, Bordetella pertussis. In this Review, we describe the pathogenesis of this disease, with a focus on recent mechanistic insights into virulence factor function. We also discuss the changing epidemiology of pertussis and the challenges of vaccine development. Despite decades of research, many aspects of B. pertussis physiology and pathogenesis remain poorly understood. We highlight knowledge gaps that must be addressed to develop improved vaccines and therapeutic strategies
